Abstract

Echinococcus granulosis is a zoonotic parasite that is the major cause of hydatid cyst or commonly called hydatidosis. Liver and lungs are the primary site where hydatidosis pathology becomes prominent. In rare cases involvement of bone is less commonly diagnosed or reported. Here in this report we present a case of sacral hydatidosis in a female patient presenting with hyrestectomy and histopathology revealed cervicitis, adenomyosis, and leiomyoma. Beside these interventions she was not improving, follow-up ultrasound was done and it was found that multioculated cystic lesions in pelvis, one in presacral region and another in RIF close to psoas muscle this lesion in RIF was connected to the presacral lesion through a narrow pedicle. Complementary CT was done and it revealed that presacral lesion has invaded and destroyed the sacrum with intra spinal extension.
